--------------
2007-08-15 11:28:01 -03:00
For the time being this module is intended to be called as a script. However it
is possible to import it into an IDE and use the function :func:`check`
described below.
.. note::
2007-08-15 11:28:01 -03:00
The API provided by this module is likely to change in future releases; such

changes may not be backward compatible.
.. function:: check(file_or_dir)
If *file_or_dir* is a directory and not a symbolic link, then recursively
descend the directory tree named by *file_or_dir*, checking all :file:`.py`
files along the way. If *file_or_dir* is an ordinary Python source file, it is
checked for whitespace related problems. The diagnostic messages are written to
standard output using the print statement.
.. data:: verbose
Flag indicating whether to print verbose messages. This is incremented by the
``-v`` option if called as a script.
.. data:: filename_only
Flag indicating whether to print only the filenames of files containing
whitespace related problems. This is set to true by the ``-q`` option if called
as a script.
.. exception:: NannyNag
Raised by :func:`tokeneater` if detecting an ambiguous indent. Captured and
handled in :func:`check`.
.. function:: tokeneater(type, token, start, end, line)
This function is used by :func:`check` as a callback parameter to the function
:func:`tokenize.tokenize`.
